纤维素自组装纳米粒子的研究进展

Research Progress of Cellulose Self-assembly Nanoparticles

针对纤维素自组装纳米粒子(CSANPs)中两亲性纤维素聚合物的骨架结构、疏水侧链和自组装响应类型进行了归纳,并介绍了CSANPs在不同条件下的粒径、形态和结构。CSANPs普遍具有智能响应性能(如温度、pH值等),在智能材料和生物医学领域有重要的应用,尤其在可控药物释放方面。新型的微观结构、尺寸、形态可控的且具有光、磁、热、生物学等性能的可降解CSANPs正成为纤维素材料领域的研究热点。

The backbone, hydrophobic side chain, and responsive type of the amphiphilic cellulose copolymers that form cellulose self-assembly nanoparticles （ CSANPs） were summarized. The particle size, morphology and structure of CSANPs under different conditions were introduced, too. Owing to the intelligent responses, CSANPs have important applications in the areas of intelligent materials and biomedicine, especially in drug carrier and controlled release. Biodegradable CSANPs with controllable morphology and intelligent responses （ light, magnetism, pH, temperature, biology, etc. ） are becoming the research hotspot in the field of cellulose materials.
